PDB format - PDBx/mmCIF conversion service

You can convert a molecular structural data into another format. The type of uploaded file is determined automatically. When the type is mmCIF and PDB format, it is converted into PDB format and mmCIF, respectively. The gzip compressed files that end ".gz" of the name, are also available. When they are gzipped, the converted files are also gzipped.
